The 100 cement or other suitable composition, suitfree ends of the springs are bent outwardly ably reinforced, as shown at 2, and formed and in some instancesupwardly, as seen at with steps or shoulders or abutments 3, 3 .24, the inner ends of the springs bearing and 4, 4, upon different levels.

The bolts 12 pass 'loosely through yopenings, in they fiat portions ofthe springs, as seen in Fig. 2, so as to allowof the requisite vertical movement of the parts without binding. Y

The parts are readily assembled, the rectangular vportion being placed upon the base, the springs then applied and then the top or capy portion 7 put in position, and the bolts 12, preferably also previously applied, with their heads countersunk in the under face of the base and their other ends passed through the springs and the top or cap portion and the metal plates 11', have the rail fastenings applied and then the 'parts are all secured together by means of the nuts 17.

It will thus be seen that provision is made for ready adjustment, as well as for separa,-
